From 482e7db160df713a2d1d4c7ee9fffad92008283f Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 20 May 2014 11:17:54 -0700 Subject: mfd: twl4030-power: Add support for board specific configuration With the recommended twl4030 configuration added, we can now add board specific changes as modifications to the recommended configuration. Note that the data is private to this driver, and the data must always have a NULL resource in the sentinel.
